. To all whom it may concern:

Beit known that I, LYMAN H. Gone, a citizen of the United States,residing in Fitchburg, in the county of Worcester and CommonWea-lth ofMassachusetts, have invented a new and useful lmproveinentin Safety-Razors, of which the following is a specification, accompanied bydrawings formlng a part of the same, in wh1ch holding the cutting bladein position, and

' firmly against the cutting tween them.

Fig. (3 is a central sectional view of the head of the razor and one endof the handle.

Similar reference letters and figures refer to similar parts in the dliierent views.

My present invention refers to thatclass of safety razors comprising ahead. for holding a cutting .blade, and mounted on the end of a handle,said head consisting of a pair of clamping plates between which thecutting blade is held in position. I

My present invention has for its object to provide an improved meanswhereby the cutting blade may be securely clamped into position orreleased at will by a single operation, and it consists of introducinginto the head 'of the razor a clamping cam provided with a lever handlewhich, by a partial ,r evolution, serves to crowd the clamping platesblade held be Referring to the accompanying drawings,

.1 denotes the handle and 2 the head of the safety razor embodying myinvention. The head consists" of a clamping plate 3 .bent at rightangles at 4c and 5 and returned upon itself forming a flange 6, and theplate 7 attached by a screw 8 to the end of the handle. Between theplates 3 and 7 is clamped a cutting blade 9. The blade 9 is insertedbetween the plates 3 and 7, and the plates are drawn together by meansof a rotating cam 10 turning freely on the end of the handle, andinserted between the clamping plate 7 and the flange The flange (l iscapable of a sliding mo ant on the handle, and is provided with a Jedrib 11, forming a cam surface coiiperamig with a corres muding camsur-Specification of Letters Patent.

face 12 on the under side of the cam 10. The cam 10 is provided with alever handle 13, having a depending lug 14, which enables the cam to berotated by the pressure of'the thumb or fingeragainst the lug. l Vhenthe raised rib 1-1 on the flange G is brought to correspond with therecessed cam surface 12 on the cam 10 the cutting blade 9 will bereleased, and by turning the cam into position shown in Figs. 3 and 4:the opposing cam surface crowds the flange 6 downward and draws itsconnected clamping blade 3 firmly against the upper surface of thecutting blade 9. In its clamped position the lever 18 and lug 14: arepushed back against the rear side of the head entirely out of the way ofthe cutting edge of the blade 9, and not interfering with the free useof therazor.

I claim, 7

.2. In a safety razor, thecombination with a handle and a clamping plateattached to one end of said handle, of a second movable clamping platebent around one edge of said attached clamping plate, and having aflange parallel to said movable clamping plate, and a cam interposedbetween said flange and said attached clamping plate for drawing saidclamping plates together.

3. In a safety razor, the combination of a handle, a clamping plateattached to the end of said handle, a movable clamping plate on i oneside of said attached clamping plate and having a flange integraltherewith and extending across the opposite side of said attachedclamping plate, a cam surface on said fiange,-and a camrotatable aboutthe handle and cooperating with said cam surface.

4. Ina safety razor, the combination of a handle, a clamping plateattached to said handle, a movable parallel clamping plate, and a camrotatable about the axis of the handle, whereby said clamping plates aredrawn together.

In a safety razor, the combination of a handle, a clamping plateattached to said handle a movable clam nn )late oarallel 7 c ,t with oneside of said attached clrnnpmg plate, a cam rotatable around said.handlc'on cam surface cooperating with said rotatable cam,

6. In a safety razor, the combination with a handle, a clamping plateattached to said handle, a movable clamping plate on one side of saidattached clamping plate, a cam 10 rotatable about said handle on theopposite" side-0f said attached clamping plate, an & op
